Abstract
A method and device for improving the efficiency of mechanical transplanting, wherein seedling balls carrying no seedlings or undersize seedlings are automatically removed prior to the planting stage. Several seedling balls are simultaneously extracted from a common cultivation tray and deficient balls are detected and removed. The deficit caused by a removed seedling ball is compensated by momentarily increasing the rate of feeding balls from the tray. No separate replacement seedling supply is required.
